DISINFEGTING APPARATUS.

Specification of Letters Patent.

Patented Nov. 1, 1910.

To all whom it may concern:

Be it known that I, CHARLES B. RIDER, citizen of the United States, residing in Ocean City, State of New Jersey, have invented certain new and useful Improvements in Disinfecting Apparatus, of which the following is a full, clear, and exact de scription, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to and has for its object the provision of mechanical means, applicable to a spittoon, sewage pipe, water closet, urinal and any like device capable of being flushed with water, for automatically supplying to such device, in admixture with the flush-water, a disinfecting or sterilizing fluid, or both, either gaseous or liquid.

To these ends my invention consists of a mechanical device having the novel and dis tinguishing features of construction and operation hereinafter described and pointed out, attachably applicable to devices of the character above referred to, whereby a disinfecting fiuid, either gaseous or liquid, is automatically admixed with flush-water and the admixture discharged into the device to be disinfected.

In the accompanying drawings illustrating. my invention: Figure 1 is a front elevation of my device coupled up with the usual source of water supply, on a dental cuspidor. Fig. 2 is a plan and Fig. 3 a vertical sectional view of my device. Fig. 4: is a section on the line w-w of Fig. 3. Fig. 5 is a plan view partly in dotted lines, looking down on the line 3 of Fig. 3; and Fig. 6 is a plan view of a soluble tablet adapted to be used with my device.

Referring now to said drawings: 1 indicates a cup-shaped vessel, shown with a cylindrical exterior wall, an open top, a centrally-disposed vertical tube 2, preferably integral'with the cup, and a short depending tubular neck 3, also preferably integral with the cup. The central tube is in alinement with the depending neck, and both are centrally recessed to form a continuous tube, care being taken that the upper terminal of the tube shall not project above, but rather slightly below the horizontal plane of the top rim of the cup, in order that the removable cap 3* and its thimble 4 may be put in place on the cup, with the thimble covering the upper end of the central hollow tube 2, as shown in Fig. 3.

Over the open end of the central tube 2 is slipped a tube-shaped wick 4* preferably with a closed upper end, for the purpose of leading, by capillarity and aiding in controlling the delivery 0 the liquid contents of the cup over and into and through the tube 2, and I prefer to provide the latter, on its exterior wall, with longitudinal flutes 5. The closing cap 6 is centrally apertured to receive the thimble 4. The latter has an airvent 7 at top, and may have a lifting-ring 8. This thimble is vertically adjustable in the aperture of the closing cap 6, and is of such internal diameter that it may pass over the top of central tube 2 and over tubular wick 4, holding the latter in place on the former. The wall of tube 2 near its top is provided on opposite sides of its periphery with two or more longitudinal slots 9, providing additional means of communication with its in terior, and these slots 9, and the wick over the same, are covered to a greater or less extent by the lower end of the thimble 4 which, as before stated, is verticall adjustable in the closing cap 6 and fits s eeve-like over the upper end of the tube 2.

The cup, its central tube, and the closing cap may be constructed of glass or porcelain if preferred, or indeed of metal, depending somewhat upon the character of the uses to which it is applied.

The neck 3 of the cup may be in a single piece, but preferably in two pieces 3, 3", connected by a sleeve-coupling 3, in order that 3 may be made a part of the injector and water supply and delivery element about to be described. The latter consists of a chamberedbody 10, in one end of which is disposed a water-discharge pipe 11, suitably shaped to discharge into the cuspidor 12 and flush it; said discharge pipe having its inlet end of usual and Suitable shape to co-act with the discharge nozzle of an injector device. The opposite side of said chamberedbody 10 is provided, in alinement with aforesaid pipe 11, with an injector nozzle 13, screwed into the wall of said body 10, with its inlet end, coupled at right angles, by means of globular coupling 14, with the water supply tube 15 having two threaded ends adapted to be coupled up with the usual valve-controlled water-supply pipe 16 of a dental cuspidor (see Fig. 1), such supply pipe 16being, as usual in such case, a vertically-disposed pipe, with suitable branches, rigidly mounted on and forming a part of the cuspidor-supporting frame. One of these branches extends upward with acurved nozzle-end discharging into the basin, and is usually supplied with a spigot, these parts being as indicated in righthand side of Fig. 1. Hence the latter and pipe 16 support my device rigidly and in appropriate relation to the cuspidor to discharge into and flush the same. In dental cuspidors such as indicated in the drawings, the main water-supply pipe 16 is governed by a spigot of any ordinary character mounted in any part of its vertical length.

As applied to a dental cuspidor I prefer to make the chambered-body 10 of my device of such exterior shape that it may rest on the annular rim .12 of the cuspidor (see Figs. 3 and 1). If desired a supporting bracket 17 may be added.

The operation of the device is as follows The cup 1 is to be filled with water, into which is placed a soluble solid or any other chemical body operating, in solution,

as a disinfecting fluid or that will produce a cup having a central tubular outlet within gthe same, said avick being fitted over said tube, means to a disinfecting gaseous body miscible with water. The wick, governed by the ralslng or lowering of the thimble, will aid in dis-v charging such solution or gas into and through central tube2 leading to the chambered-body 10, and will also control its delivery thereto in case the suction created by the injector would otherwise be too great. The water discharged into the chamberedbody 10, from the usual source of supply 16 of the cuspidor, through the injector device, prior to its discharge therefrom to the cuspidor, through pipe 11, will be admixed with the incoming disinfecting solution or gas from cup 2, and the injector device in said chambered body will not only accelerate the incoming flow of water from pipe 11, but will create a partial vacuum or suction in the chambered body sufficient to aid the wick in drawing disinfecting solution or gas from the solution cup 1 above it. And the chamber'ed body 10 is of larger area and of hemispherical or other similar shape, so that it may always contain, below the horizontal plane of the injector elements, a small body of the admixed disinfecting solution. For convenience I may use a tablet 17 (see Fig. 6) of some soluble chemical, with a central aperture 17 whereby it may be slipped over the central tube 2 and over the wick therein.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. The combination with a receiving cup having an interior inverted discharge-tube, an exterior tubular neck at the base of the cup, in alinement with said interior tube, means to vent the cup and means to adjustably control the admission of liquid to the open end of the discharge-tube, a mixingchamber disposed below said cup and its tubular neck, inlet and discharge pipes leading to and from said mixing-chamber, and an injector-nozzle and combining tube mounted thereon, respectively, in spaced relation, within said mixing-chamber. I

2. The combination with a receiving cup, an apertured closing cap therefor, a thimble vertically adjustable in said aperture, a central tube in said cup, peripherally slotted near its upper end, a basal hollow neck on said cup, in alinement with its central tube, a tubular wick fitted sleeve-like over the latter, a mixing chamber below said cup and its adj unctive elements, and means to discharge a current of water through said mixing S5 chamber in a direction transverse to the superposed cup and its discharge tubes.

3. The combination with the receiving tube being fluted, a tubular hold said elements in operative register, a

'basal aperture in said cup 1n alining communication with the central tube thereof, a mixing chamber below the cup, an injector device in said chamber, and means to convey water to and discharge it from the elements of said injector device.

4:. The combination with a mixing chamber, comprising a chambered body, an injector nozzle and its combining tube mounted horizontally within the same, a water discharge pipe leading therefrom, a water inlet pipe leading to the same, with means on the projecting end of the latter adapted to couple it to a fixed source of water supply, a. receiving cup operatively supported over said chambered body, adapted to contain a disinfecting solution, and an inverted open-ended discharge tube centrally disposed in said cup and communicating at its base with said chambered body over said injector device therein;

In testimony whereof, I have hereunto affixed my signature this twenty-ninth day of October A. D. 1909. v
